Building on Mac OS X 10.5 has many similarities to building on RHEL5 64bit but does have some issues of its own. One should read this post before installing ANYTHING, since there are issues which affect every package.
One must also install the gfortran compiler which can be found here.
Universal binaries can be built for many packages. I have tag such packages with “universal.” One accomplishes this task by simply prepending:
env CFLAGS="-O -g -isysroot /Developer/SDKs/MacOSX10.5.sdk -arch i386 -arch ppc" LDFLAGS="-arch i386 -arch ppc"
before the configure option.
